Buick is adding a turbo variant this fall as the premium model for the Verano lineup.

While it's meant to be sporty, the idea behind the sedan is to offer buyers a reasonably powerful option that allows for more amusing commutes, but admittedly, it isn't a dedicated performance model.

This is a measured approach, which means extra output for expressway merges and launches from lights, but no hard-core suspension or brake packages. It does get a dual exhaust, a rear spoiler and sportier aluminum-and-rubber pedals.

The key feature is the 2.0-liter four-cylinder borrowed from the Regal GS, which does purport to be more of a sporting machine. The engine makes 250 hp and 260 lb-ft of torque in the Verano, enabling sprints to 60 mph in a claimed 6.2 seconds. It's paired with a six-speed automatic or manual transmission.

That's a considerable power boost compared with the naturally aspirated 2.4-liter, 180-hp, 171-lb-ft I4 offered now. The turbo variant also gets a retuned suspension and steering feel, which will be slightly more responsive than in other Veranos. But the entire line, which just launched late last year, is getting adjustments based on the turbo model's chassis settings.

The Verano takes aim at the Audi A3 and the Lexus IS250 as aspirational targets, while setting the Acura ILX squarely in its sights. The turbo will be the top model in performance and pricing among Veranos, and precise prices will be announced closer to the on-sale date this fall.

Buick has sold 11,578 copies of the Verano this year, including 3,609 cars in May.
